Your host wants to move you to a newer PHP version
The application was written for PHP 5.6 or 7.x and nobody knows what will break on PHP 8.
CodeIgniter 2 / 3 support & maintenance
CodeIgniter 3 support for systems your business still depends on.
We keep CodeIgniter applications running, fix what is broken and make them compatible with current PHP versions, without forcing a rewrite.
For companies whose CodeIgniter system handles real customers, orders, bookings or reports, and who need a reliable technical owner for it.
CodeIgniter 2 and 3
PHP 5.6 to PHP 8.x
No forced migration
Typical situations
CodeIgniter 3 still works. Keeping it working is the hard part.
Most CodeIgniter 3 systems were built years ago and kept growing. The framework is stable, but the environment around it keeps moving.
The logs are full of warnings and errors
Deprecation notices, undefined index warnings and occasional fatal errors that nobody has time to investigate.
Nobody wants to touch the code
New developers prefer modern frameworks, so small changes take weeks or never happen.
Security has not been reviewed in years
Old libraries, custom authentication and file uploads that were never checked against current threats.
What we do
Practical CodeIgniter maintenance.
We work inside your existing CodeIgniter application. We do not replace it with something new unless you decide that is the right business move.
PHP 8.x compatibility
Older CodeIgniter 3 code often relies on behaviour that newer PHP versions deprecate or remove, for example dynamic properties, passing null to built-in functions or old mysql_* calls. We find these issues in the framework and in your own code, fix them and test the critical workflows before the switch.
Bug fixing and small features
Clear fixes for the problems your team reports, and small improvements that keep the system useful, delivered with care for the parts that must not break.
Security and stability
- Review of authentication, sessions, file uploads and database queries
- Updating or replacing outdated libraries
- Backups, error logging and monitoring that actually get looked at
Ongoing technical ownership
One accountable technical owner who knows the system, keeps notes on how it works and is there when something goes wrong.

FAQ
Frequently asked questions.
Is CodeIgniter 3 still safe to run?
It can be, if it is maintained. The risks usually come from an unsupported PHP version, outdated libraries and custom code that was never reviewed. We check those areas first and fix the most dangerous ones.
Will our CodeIgniter 3 application work on PHP 8.x?
Often not without changes. Older CodeIgniter 3 projects and their custom code commonly produce deprecation warnings and fatal errors on PHP 8.x. We find these issues, fix them and test the critical workflows before you switch.
Do we have to migrate to CodeIgniter 4 or Laravel?
No. A migration only makes sense when there is a clear business reason. Many CodeIgniter 3 systems can run safely for years with proper maintenance and a supported PHP version.
Do you also support CodeIgniter 2?
Yes. CodeIgniter 2 systems usually need more stabilization work first, but the approach is the same: protect what works, reduce risk, then plan the next step.
Can you work with code that has no documentation?
Yes. Most of the CodeIgniter systems we take over have little or no useful documentation. We document the critical parts as we go.
